Veteran Olympics broadcaster to replace Savannah Guthrie as co-host

With the search for “Today” show host Savannah Guthrie's missing mother continuing, NBC says that veteran Olympics broadcaster Mary Carillo will replace Guthrie as co-host on Friday's telecast of the opening ceremonies for the Winter Games. The mystery of Nancy Guthrie's disappearanc e — investigators believe she was taken from her Arizona home against her will — has cast a pall over what was anticipated to be a giant week for the television network. The Olympics is among the few events to still draw consistent, big audiences to broadcast television.
